重新启动xcode修复了这个问题！我讨厌你苹果：）

My problem is that I need to enable the keychain sharing feature to App ID in order to make Facebook login work for iOS10. How to use Facebook iOS SDK on iOS 10

However, I get the below message.

I have NO iPhone device. However, I do have a paid for developers account. I don't need a provisioning profile to resolve this error, do I?

How exactly can this be resolved?

Restarting the xcode fixes the issue ! I hate you apple :)
